Renewed February 11, 1908. Serial No. 415,870.

To all whom it may concern:

Be it known that I, FREDELLIA H. MOYER, of Clairton, Allegheny county, Penns lvania, have invented a new and useful Gasasher, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of th1s specification, in which.

Figure 1 is a plan view, partl in horizon-. tal cross section; Fig. 2 is a side elevation art] in vertical cross section on the line Il l of 1; Fig: 3 is an end elevation partly in section on the line IIIIII of Fig. 1; Figs. 4 and 5 are detail views on a larger scale, showing the construction of the irregular lower end portions of the depending partitions in the washer.

This apparatus is of the same general type as the gas washer shown in my pending application, Serial No. 360,029, filed March 1, 15907 and it is designed for use in locations where the circular construction shown in the nding application or other reasons make the use of that form undesirable.

The invention relates to apparatus emloyed in cleaning gases by removing finely ivlded solid im' urities carried in suspension in the gases an the object of the invention is to provide an improved form of gas washer having means by which the ases are spread into a flat thin sheet, so as to ring'the largest possible surface of the gases into contact with the fluid contained in the washer.

Another ob'ect of my invention is to rovide improved means for introducin an reremoving fluid in the washer by t e use of Which'any foreign matter on the surface of the fluid is continuously removed as it is formed and choking or clogging of the pas-' sa es for the gases is prevented.

t 'further consists in rovid' a gas washer which can be use .as a iiy dust catcher by shutting ed the fluid supply and removing the fluid 1n the lower portion of the washer without 'stoppin or retarding the flow of the gases throug the apparatus; in changing the washer into a .dust catcher, or vice versa.

In the drawings, 2 represents the rectane gular shell of a washer and 3 the gas'inlet pipe, this ipe being provided as shown with two branc inlet pipes 4 each connecting the inlet pi e 3 with-the end of the vessel 2. A

gas out et pipe 5 is also connectedby two gas outlet branch pipes 6 with the opposite end of the shell 2 of the washer. One or more branch pipes 'may be used to connect the gas washerwith the gas supply and with the gas outlet pipe.

The mterior of the shell 2 is divided by up wardl extending partitions 7 into a series of cham ers 8, these cham rs being in communication with each other by the passages formed between the top of the shellv 2 of the vessel and the top of the partition 7. Each of the chamber 8 is provided as shown with 2, depending partition 10, theseartitions extending from the top of the she 2 to within a short'distance of the level of the liquid in the washer.

Each of the chambers or compartments 8 is preferabl provided with a sloping bottom 11 and wit a cleaning opening 12 which is normally closed by means of a bell 13. As shown in the drawings, the partitions 7 which divide'the vessel into compartments extend downwardly and p are connected to the flanged bottoms of adjoining compartments. Instead of this construction, these partitions may extend downwardly to a point sufiiciently below the level of the liquid in the Washer to shut off communication from one compartment 8 to the adjoinin compartment 8 between the lower end 0 the partitions 7 and the surface of the liquid in the washer. Each of the compartments 8 is provided with a fluid inlet pipe 14, these pipes 14 being connected to a common supply pipe 15. Each of the compartments 8 is also provided with a fluid overflow trough-or funnel 16 into which the fluid flows from the washer and carries an forei n matter floating on the surface 0 the Washer and out of the path of the incoming gases. A seal for the fluid overflow openings is provided by means of the overflow pipes 17 uid out of the which extend downwardl 'from the trou h or funnels 16 to apoint be ow the level 0 the fluid in the pool of fluid which is maintained below the chamber 2.

The lower end of each of the depending partitions 10 is provided with a crim ed or uted end portion which is constructe so as to provide a passage between the end of the partition and the surface of the fluid, havin an irre ular contour in a lane parallel wit the su ace of the fluid in t e washer. By so forming the lower end of thepartitions 1G I pipe,.18 by means of which fluid is s rayed on the surface of the fluted lower en portions of the partitions 10, in this way bringing the fluid into more intimate contact with the gases and thereby removing a larger'amount of the solid impurities in the gases than would otherwise be effected.

Preferably the washer is provided with a.

series of com artments in eachof which a separate poo of liquid is. maintained, although one pool may be employed in which case the vertically extending artitions 7 will be below the level of the liquic in the washer,

a suflicient distance to prevent passage of the.

gases between the lower end of these partitions and the surface of the liquid.

When the gases are im inged on the surface of the liquid in the rst compartment, the maj or amount of the impurities will be removed and when the separate pools are maintained, the first of these compartments may be cleaned more frequently than the others, in this way reducing the amount of fluid necessary to be removed to keep the apparatus in condition.

.In the operation of my improved washer the gases from the inlet ipe 3 enter the vessel 2through-the branch in ct pipes 4 and are deflected downwardly by contact with the partition 10 and are caused to flow downwardly and impinge on the surface of the liquid in the first of the compartments 8. The gases are spread into a flat thin sheet in assing between this partition andthe su ace of the liquid and then rise upwardly on the opposite side of the partition 10 in the first compartment. The gases then pass through the communicating passage formed by the top of the washer 2 and the to of the u wardly grojecting partition 7 ant are then eflected ownwardly by the next partition 10 being again spread into a flat thin sheet and caused to again impinge on the fluid in the washer.

- The 0 eration as thus described is carried out in eac of the succeedin chambers, of which there may be any desire number.

Contact of the hot gases with the liquid in the washer will vaporize a portion of this liqliquid. By providing a constantly changing supply. of fluid used in washing in the apparatus the fluid is constantly flowing into the fluid overflow outlets.

This overflow car ries the scum as it is formed from the surface of the liquid into the outlets and downwardly season through the pipes into the pool of liquid heneath the washer and in thls way choking or clogging of the passages is prevented.

The apparatus may be provided with a re fractory lining when desired.

Mod1fications in the sha e and arrangement of the apparatus may he made without de arting from my invention.
